哪位英语高手能帮忙翻译一下？

Dear sir,
If you've already have a basic knowledge of Chinese language, we'd like to arrange you in an Intermediate Course. if not, we are sorry telling you that you have to wait for a while. Because all the beginners' classes are full, and we can't open a new one uless there are three people. we will send you the latest news.
Best wishes!

If you have a Chinese base, we can help you arrange Intermediate. But if you do not have any English foundation, very sorry to tell you, because all the Chinese places in the primary class is full, so at least three people have to wait until Minato we will re-open a class.
Because this letter is addressed to a boss, so be tactful and respectful attitude a bit. Thank you ~

I am sorry to tell you that the basic Chinese course you applied is full and you have to wait until there are two more applicants for the new basic class. I am wondering if you have some chinese base, if that is the case we can arrange intermediate course for you.
